How can I solve the problem that preventDefault forbids root-level div default event child div scroll bar scrolling is invalid?

I wrote a page to swipe up and down the page, and when I put my finger in the div range with content in the middle, I disabled the touchmove event, using {

                    //
                    e.preventDefault()
                    //
                    e.stopPropagation()
                    e.nativeEvent.stopImmediatePropagation();}

but the scroll bar of the div (the one with content) in the middle cannot be scrolled on the mobile phone. It can be scrolled on the PC. Excuse me, God, how to solve this? The code is as follows:

The

e.nativeEvent.stopImmediatePropagation (); method prevents processing of event listeners in the current node and all subsequent nodes in the event flow. This method takes effect immediately and affects event listeners in the current node. Here, you only need to deal with the current event listener, so you don't need to comment it out here, and you can bind the div object that needs to be scrolled, and bind e.stopPropagation () in a touchmove event to prevent bubbling.
